You can create a custom exception renderin the App\Exceptions\Handlerclass (in the /app/Exceptions/Handler.phpfile).
您可以在类中（在文件中）创建自定义异常渲染。App\Exceptions\Handler/app/Exceptions/Handler.php
For example, to render a different view when for the TokenMismatchExceptionerror, you can change the rendermethod to something like this:
例如，要在TokenMismatchException出现错误时呈现不同的视图，您可以将render方法更改为如下所示：
/**
* Render an exception into an HTTP response.
*
* @param \Illuminate\Http\Request $request
* @param \Exception $e
* @return \Illuminate\Http\Response
*/
public function render($request, Exception $e)
{
if ($e instanceof \Illuminate\Session\TokenMismatchException) {
return response()->view('errors.custom', [], 500);
}
return parent::render($request, $e);
}

You will need to write a function to render the TokenMismatchException error. You will add that function to your App\Exceptions\Handler class (in the /app/Exceptions/Handler.php file) this way:
您将需要编写一个函数来呈现 TokenMismatchException 错误。您将通过这种方式将该函数添加到您的 App\Exceptions\Handler 类（在 /app/Exceptions/Handler.php 文件中）：
// make sure you reference the full path of the class:
use Illuminate\Session\TokenMismatchException;
class Handler extends ExceptionHandler {
protected $dontReport = [
HttpException::class,
ModelNotFoundException::class,
// opt from logging this error to your log files (optional)
TokenMismatchException::class,
];
public function render($request, Exception $e)
{
// Handle the exception...
// redirect back with form input except the _token (forcing a new token to be generated)
if ($e instanceof TokenMismatchException){
return redirect()->back()->withInput($request->except('_token'))
->withFlashDanger('You page session expired. Please try again');
}
